Rolex Pre-Daytona (Silver Dial)

In the 1969 movie adaptation of the same name, Bond, played by none other than the legendary George Lazenby, was seen on the silver screen with a ref. 6238 on his wrist. The Rolex ref. 6238 epitomizes a turning point in the history of Rolex history of chronograph. Produced for a short period from the beginning of the 1960s to 1967, it was not only the last Rolex chronograph to feature a smooth bezel with a tachymeter scale on the dial, but also a model that paved the way to the ref. 6239.
